Miami ? Dressed to the canines, pooches are posing for professional portraits paid for by their spend-ready masters. The trend is among the latest in what has become a $29 billion pet services industry.

From “peticures” to luxury boarding houses, the portraits are only a part of a burgeoning market for upscale animal services, said Runda Alp, spokeswoman for the American Pet Products Manufacturers Assn.

Joan Saperstein tries to get Vandit, a 117-pound bull mastiff, to stand still for a portrait at Pet Star.

Cashing in on the critters: Pet Star, a photography company run by a mother and daughter duo out of their Miami area home.

Dogs, cats, ferrets, pigs and birds. Oh, and possums are welcome.

“They all think their animals are beautiful,” Joan Saperstein said of her clients.

But, well, they’re not.

Possums “are ugly little creatures,” Saperstein said, “and we still got a great picture.”

They can make a rodent look radiant? Now that’s talent.

Thirty bucks buys a 5-by-7-inch print of Fido. Other packages, some including wallet-size photos, run up to $250. They also come on wall clocks, greeting cards, T-shirts, coffee mugs, mouse pads, magnets and more. Among the options: decorating the bedroom with throw pillows adorned with your potbellied pig’s image. Charming, really.

But what to wear, what to wear?

A policeman, a cantor, a rabbi or maybe a sailor? Saperstein and daughter Lisa Meltzer, who call the company a part-time pet project, have a walk-in closet full of canine costumes. There’s chokers perfect for those long-necked poodles cat-eye sunglasses, bonnets, bow ties, beads, fatigues and straw hats.

First-time customer Bailey, a poised bull terrier, is used to leading a pampered life. She eats only raw meat and regularly undergoes acupuncture therapy.

“She’s my money pit,” said her mother, Maruchy Perez.

Perez and Bailey opted for matching purple boas and pink feathered headbands for their recent portraits. Think Spuds MacKenzie turned flapper.

Bailey was rather camera-shy: “She emits a little gas when she gets nervous,” Perez said.

Must have been really nervous.

The American Pet Products Manufacturers Assn. estimates Americans will spend $29.5 billion this year on their pets on everything from treats and toys to grooming and pictures.

That figure is $6.5 billion more than was spent five years ago.

“More so today than ever before, we’re seeing that we are treating our pets like part of the family,” Alp said. “There’s been an evolution since the days when they were relegated to the back yard. People are much more willing to splurge on them, because it’s their way of treating them like any other family member.”

Among the indulgers: preschool teacher Sally Duncan.

“Perk up your ears, kid,” Duncan called out to her rat terrier, Cody, at a photo shoot.

Duncan wanted the classic portrait; no fancy frills or bows. This shot was for Cody’s 94-year-old grandmother.

“An easy one,” Meltzer said of the pooch’s good manners. Cody fancied himself a Casanova in front of the camera. On cue, the canine straightened his neck and, his mother insisted, “smiled.”
